THUNDER BAY, ONTARIO--(Marketwire - May 3, 2011) -Source Exploration Corp. ("Source" or the "Company") (TSX VENTURE:SOP) is pleased to report encouraging preliminary results from the initial drill program at the Company's Las Minas project located in western Veracruz, State, Mexico. The holes were drilled as part of a Phase 1 program to define primary targets for a planned expanded drilling program and to test the strike extension of mineralization outlined by Source's recent sampling program. To-date drilling has intersected mineralized zones hosting significant gold, silver and copper values extending up to 180 metres beyond the historical mine workings at El Dorado. These zones have apparent widths of 15 to 30 metres in thickness and have been delineated over a strike length of more than 300 metres.

Brian E. Robertson, Source Exploration's President and CEO stated, "We are very encouraged by these early drilling results and the discovery of extensive mineralized zones at Las Minas that contain significant gold, silver and copper values. On-going drilling continues to delineate significant mineralization over appreciable widths; assays will be released as they become available. Future drilling will test the high priority targets including the Cinco Senores, Las Minillas and San Jose de Oro mineralized zones as part of the Phase 1 drill program.

Phase 1 Drilling Program.

The Phase 1 drilling program at the El Dorado and Las Boquillas zones has focused on the potential extension of known zones beyond the historical mine workings and the potential along strike. Drilling at El Dorado indicates a strongly mineralized zone that extends up to 180 metres beyond the historical mine workings and remains open on strike and down dip. Assay results for eight holes remain pending. The mineralization at Las Boquillas may represent the on-strike extension of the El Dorado zone. Current drilling and rock chip sampling results reported in earlier press releases have indicated that the zone may extend up to 2 kilometres along strike.

The planned Phase 2 drilling program will test the full extent of the mineralization by infill drilling between the Las Boquillas and El Dorado zones as well as step-out drilling along strike. A plan map showing the drill site locations at Las Boquillas and El Dorado can be viewed on the Company's website at www.sourceexploration.com – see Project – Maps.
